pandas.api.types.is_timedelta64_ns_dtype(arr_or_dtype)
[source]
Check whether the provided array or dtype is of the timedelta64[ns] dtype.
This is a very specific dtype, so generic ones like np.timedelta64
will return False if passed into this function.
Parameters: |

---|---|
Returns: |

>>> is_timedelta64_ns_dtype(np.dtype('m8[ns]')) True >>> is_timedelta64_ns_dtype(np.dtype('m8[ps]')) # Wrong frequency False >>> is_timedelta64_ns_dtype(np.array([1, 2], dtype='m8[ns]')) True >>> is_timedelta64_ns_dtype(np.array([1, 2], dtype=np.timedelta64)) False
